"Build a playbook" is the most repeated advice in trading and the most poorly executed. Most playbooks are Notion pages of charts with arrows. That's a mood board. A real playbook is a decision tree: if these conditions are present, take this trade at this risk, exit at these criteria.
The 5-field playbook entry
Every setup in your playbook needs exactly five fields. More and you won't maintain it. Less and it's not actionable.
- Name. Short. "London open reversal." "Earnings IV crush." Searchable.
- Trigger conditions. Bullet list. Each bullet is binary — true or false, no judgement.
- Entry, stop, target rules. Mechanical. "Enter on close above prior 15m high, stop 1 ATR below, target 2R."
- Invalidation. The condition under which you do not take or do exit the trade. This is the field most playbooks skip and it's the most important.
- Historical expectancy. Pulled from your journal analytics filtered by this setup tag. Updated quarterly.
How to find your first 3 setups
Export your last 90 days of trades. Sort by P&L. Look at your top 20 winners and identify what they had in common — instrument, time of day, market context, pattern. That's setup #1. Repeat with the next cluster. Stop at three. You don't need a library of fifty — you need three with positive expectancy you can take in your sleep.
The trigger test
Give the playbook entry to another trader. If they can't apply it without asking you a question, it's too vague. Tighten the conditions until two people would take the same trade.
The maintenance cadence
Every quarter, recompute expectancy per setup. Tag setups with R-expectancy bands: green (above +0.5R), yellow (0 to +0.5R), red (negative). Green setups get more size; red setups get retired or rebuilt. The playbook is a living document, not a tablet from a mountain.
Where the journal fits
Every trade gets tagged with a playbook setup at entry. If you can't pick a tag, you don't take the trade — that single rule eliminates more bad trades than any other discipline. Your analytics then group performance by tag automatically, and the playbook self-grades.
A playbook isn't art. It's an operating system.
